Surface Processing

Since Neodymium type rare earth magnets rust easily compared to the Samarium Cobalt type, surface treatment is generally utilized on Neodymium type magnets. Although various methods to treat the surface of Neodymium magnets exist, Shin-Etsu has pioneered the development of, and was the first in the world to succeed in implementing the nickel electroplating method of surface treatment. Currently, nickel plating has become the standard method for Neodymium type magnets in a clean environment. We also develop and provide various surface treatments such as electro- and electroless nickel plating, epoxy coat, inorganic coat, RX coat, T-LEX coat, and RHEM coat, customized to requirements.
